vHEATER ATTACHNIENT FOR LOCOIVIOTIVE-INJETORS.

SPECIFICATION forming paf@ 0f LeteIS Patent NO.. 689,943, dated December 31, 1901.

Application filed September 27. 1901. Serial No. 76,769. (Model.)

zen of the United States, residing at Wadsworth, in the county of Medina and State of Ohio, have invented a certain new and useful Improvement in I-Ieater Attachments for Locomotive-Injectors, of which the following is a full, clear, and exact description.

The object ofthis invention is to somodity the construction and operation ot' a hot-water injector, particularlyone for use on a locomotive, that the steam maybe diverted through the injector into the suction-pipe and thence into the tank in a volume sufficient to heat the Water in the tank. l

In carrying out myinvention I provide for closing the injector-overflow when steam` is admitted into the injector and controlling at the same time the steam-valves, so as to cause the steam to pass to the suction-pipe and tank, as above indicated.

The more perfectly to `illustrate this inven-1 tion, reference is made to my inventions in Patents No. 495,286, dated April 1l, 1893, and No. 649,265, dated May 8, 1900, which show the general character of injectors to which it is applicable.

In carrying out my invention the overiiow-` I-Iaving thus stated the principle of my in vention, I will proceed now to describe the best mode in which I have contemplated applying that principle and then `will particularly point out and distinctly claim the part, improvement, or combination which I claim as my invention.

In the accom panyingdrawngs, illustrating myinvention, in the several figures of which like parts are similarly designated, Figure 1 is a side elevation of one form of locomotiveinjector to Which my invention is applied. Fig. 2 is avertical longitudinal section of the same. Fig. 3 is a side elevation, and Fig. 4 is an end elevation, ot' the auxiliary operatingdevice for the main steam-valve with parts in position to inject water into the boiler; and Fig. 5 is a side elevation, and Fig. 6 is an end elevation, of lhe same parts in position when used as a heater. Fig. 7 is a longitudinal section of the parts of and as shown in Fig. 5.

I will proceed now to describe my invention, as illustrated in the drawings, as embodied in a hot-water injector for locomotives, but without thereby limiting my invention to this single application thereof, and expressly reserving the right to claim the invention wherever applicable. The casing 2 is of approved construction, having a steam-inlet 3, a suction-tube 4, an overflow 5, and a boiler connection 6. Other parts that are as usual and substantially such as shown in the patents referred to are the compound steamvalve 7and teaser Sand their respective seats, the steam-valve stem 9, the forcing-tube l0, the vertically -reciprocating overiow valve 1l, the check-valve 12 in the boiler connection, the steam-valve 13, operating in conjunction with the steam-.jet 1l next the suction-tube, and the lifting-tube 15, with appropriate duid-passages.

The main steam-valve 7 has its stem 9 connected by a yoke 16 with a lever17, having a pivoted fulcruzn-piece 1S, and this lever is also connected by links 19, pivoted fulcrum 20, and links 2l with the stem ofthe overflowvalve 1l, so that the operating mechanism of the steam valve also actuates the overowvalve. The stem 9 is provided at its outer end with a handle 22, having a screw-socket 23, whereby it is applied to the stem, and upon this socket-piece 23 is mounteda sleeve 24:, having opposite L-shaped slots 25 and also a stop-notch 26. The sleeve has its position upon the socket-piece, and consequently upon the stem, relatively fixed by means of a nut or other abutment 27 next the injector-casing and by means of the engagement of the handle 22 with the outer end of said sleeve and its notched stop and theinner'angularend of the slots 25 in said sleeve, so that in either position the movement of the sleeve by means of the valve-operating mechanism, including the lever 17, `will be transmitted to the stem, and consequently to the steain-valve.

The stem 9 is swiveled to the steam-valve, and the sleeve 2t is rigidly connected with IOO the yoke 16, so that the said stem may have movements in the direction of its length independent of the movements imparted to it by the yoke 16 and lever 17, and this independent movement is effected by engaging the handle 22 and pulling'it outwardly .until itengages the notched stop at the outer end of the sleeve or by giving ita partial turn, so as to slip into the slots ofthe sleeve, the rcspec tive positions being illustrated in Figs. 3, 4, and 6.

The operationis as follows: To start the injector, the lever ispulled back or to the left, Fig. 1, a short distance, and the main steamvalve 7 is thereby raised slightly from its seat and sufficient to admit steam to the teaser 8, whereby Water is lifted, and then the lever 17 is pulled backits full stroke and steamis adminted to the injector, and simultaneously the overflow-valve is closed, and the handle 22 is in the position shown in Figs. 1, 3, and 4. Tater will now pass to the boiler. Ifit be desired to heat the Water in the tank, then the handle 22 is turned unt-il it is in alinement with the slots 25, and then it is pushed into these slots and locked in their angles, as in Figs. 5, 6, and 7, and this movement of thehandle serves to push in the valve-stein 9 a distance sufficient to cutoff a full flow of steam and yet admit steam to the teaser, and since the overflow is closed the steam thus admitted in a small quantity passes to the suction -tube and thence tothe tanlr,and so heats the water in the tank. In other Words, by means of the attachment illustrated in detail in Figs. 3 to 6 it is possible to change the distance between the overflow and the main steam-valve and teaser, so that the main valve is raised from its seat to ad mit steam to the teaser, but not sufficiently to unseat the teaser, and at the same time the overflow being closed the steam passing through the valve or teaser will not escape at the overflow, but will pass down the suction pipe or tube into the tank. Thus the teaser admits just steam enough to answer the purpose ofaheater, while the fulliiow of steam would be too much.l

What I claim is- 1. In a steam Water-lifting apparatus, such as an injector, a main steam-valve, an auxiliary steam-valve or teaser, an overflow-valve, primary operating means common to all, and a supplemental actuating` mechanism comprising a relatively fixed slotted sleeve, and a coacting handle connected with the stem of the main steam-valve and adapted to actuate said valve independentlyof the primary operating means, to decrease the [low of steam without affecting the position of the auxiliary steam-valve and the overflow, thereby to divert the steam to the water-supply to heat the water therein.

2. In an injector, a suction-tube, an overiiow-valve, a main steam-valve and its teaser, primary operating means common t0 the steam-valves and overiioW-valve, and an attachment for independently actuating the main steam-valve Without affecting the positions of the teaser and overflow-valve, and com prising essentially a relatively fixed slotted sleeve applied to the primary operating means and a handle applied to the stem of the main steam-valve whereby said valve may be adjusted with relation to said relatively Xed sleeve to change the relation of the vmain steanrvalve to its seat.

8. In an injector,a steam-valve,comprising a main valve and a teaser, an overiioW-valve, actuating mechanism for these valves, and an independent operating device for the main valve, comprising a relatively fixed sleeve provided With l...-shaped slots and a stopnotch, and a handle on the main-valve stem movable with relation to the said sleeve, and adapted to be fixed relatively thereto in either of two positions,so as to adjustthe main steamvalve to admit a full How of steam for supplying the boiler with Water, and to reduce the supply of steam and divert it to the Water-supply.

4f. In an injector, a steam-valve, actuating mechanism therefor including a stem, -provided with an abutment, such as a nut, a sleeve mounted upon the said stem and against such abutment and fixed relatively to the valve-actuating mechanism, the stem being capable of being turned Within the said sleeve and provided with a transverse handle adjacent the outer end of the sleeve, and the said sleeve having a stop-notch and also longitudinal slots with which the said handle cooperates.

In testimony whereofl have hereunto set my hand this 24th day of September, A. D. 1901.
